AApplication ined July .16,

This invention relates to flashing retainers, and the obJect is toprovide a new and improved means for securing a lashingto ar wallorchimney. l Y

Heretofore, in this art, especially with met al roofing, it has beencominon'practice where the roofing contacts the sideface of a wall or achimney to extend the'metal a short distance and insert the edge in agroove commonly termed a raglin, provided between courses of bricks andsecure the saidedge therein by means of wedges. Suchpreviousmetliod isinadequate in that the wedge members become loosened after la period ofilse and the in# sei-ted edge of the roofing becomesfdisplaced and it isalsoa rather expensive operation to secure the edge of therooling inplace in the manner stated.

My present invention seeks to obviate these various difficultiesVarising 1n theprevious methods andy t'o provide a separate channeledAmember which is laid in place between two courses of brickor stones atthe time of erection of the wall providing a recess into which the edgeof the roofing member may be readily yinserted and avoiding the laborinvolvedin removing la portion of the mortar, the member being hanged toengage over and securelyy fasten the flashing in place therein thuskavoiding the use of wedges.

These objects and the various novel features of the invention Aarehereinafter more fully described and claimed,` and the preferred form ofconstruction of a flashing retainer embodying my invention is shown inthe accompanying drawings in which- Y Fig. 1v is a sectional View of aroof and a parapet showing the general arrangement of the flashing andflashing retainer.

Fig. 2 is an enlarged sectional view thereof at the time the edge of theflashingis in- Ytroduced into the flashing retainer.

Fig. 5 is a section longitudinally of two such strips whichV areinserted endwise one in the other laying a flashing of greater lengththan a single strip.

Fig. 6 is an alternative form of construction.

My improved flashing retainer consists of al member'l which ispreferably made of a copper sheet turned upon itselfto provide a nar-1927.1 semi ne. 206,183, f

in width than the thickness ofthe metal sheet or. flashing tobefinserted therein. y One of the edgesy 3 of this strip is bentapproximately at a right angle outwardly as shown and the other edge 4is also bent at a ,slight angle l lrow channel indicated at2 butslightlygreater in the saine directionas tlielmember 3 providing a comparativelywide throat for `the l.space The sheet in its two opposite side .wallsis punched at regular intervals longi-l tudinally'of the strip asindicated in Fig.4

to provide inwardly extending points 6. and 7 which are in registrationwhen the ksheetfis folded and provide a means for holdingl the y,

two side walls ofthe retainer in the desired spaced relation, thepurpose being to prevent 'the walls of the flashing from being forcedtogether when laidin the mortar yand under pressureof. the brick orvstone thereabove.v These retainer strips are preferably made of copperin. order thatthey, shall berustproof Y r`and provide permanentinstallation so that,

even tho the flashing introduced therein may rust out, the retainerbeing la permanent inrstallation is used when the roof is repaired andthe edge of a new sheet introduced-there.-

in. `Preferably the inner face ofthe strip forming thechannelis turnedor galvanized to prevent adherence of the flashingther'ein. lt will bereadily l'understood :from the drawing that in the laying of the wall orthe` chimney with which the flashing retainer is to be used, it islaidupon the brick orstone as the case'may be at the desired heightabove Ythe roof usually about six to eight inches and the wall .is thereaftercompleted in the usual way. Vhe'n laid in the wall lthe member ispractically as shown in Fig. 2 with the edges 4 and 5 in the spacedrelationas is shown in Fig. 4 which is vthe form at the time of infstallation providing a wide guide opening or 'throat for introduction ofthe edgev 8 of the roofing sheet `9. Usually Vsuch metal roofing y islaid over 4one or more layers fof roofing paper indicated at 10 whichextend across Athe roof surface and for a distance up the face of thewallas indicated at 11. Themetal roofing lplate 9 lays thereover andextends upward :along the side wall or chimney or -otlierfstructureastlie case may be and the 3 thus efiectually securing the flashing inplace andV eifectually preventing any ac-y cidental removal or leakage.

As previously stated, the flashing member; l is made preferably inunitorm lengths ot from six to eight feet and, for use in wallsmannerfor a short distance the purpose bei ing to prevent any break in thecontinuity of the flashing ietainer although it is to be understood thatthe invention is not confined to such use of the parts.

In Fig. 6 I have shown an alternative form of construction of theretainer. lith this form the upper wallet the strip extended as atlObeyond the lower wall which extends to approximately a point indicatedat 1l and at the opposite end the lower wall is'extended as at l2 beyondthe end ot Vthe upper wall at 13. The length of these extending portionsmay be as desired but preferably not more than two inches.A In layingsuch strips in endwise relation the extending end portion yLl 10 of theupper wall lays over the extending portion l2 of the lower wall of theadja cent strip and thus the joint which would then be formed betweenthe end 100i' one strip and the end 13 of the adjacent strip does notalignl with the joint between the adjacent ends of the lower vwalls 1land l2 as will be readily understood. Also, iii the laying of the metalroofing the joints between sheets thereof should bieak joints with thejoints in the flashing retainer. This insures prevention of leakage. V

In the construction of the retainer the depressions may be of muchgreater area than shown in Fig. l and of a form 'for instance assuggested in Fig. 6 at lll. These provide pockets in the outer faces ofthepwalls of the retainer in which the mortar engages and as thesedepressions are preferably formed in both walls, as in the forni shownin Fig. l, the projections thereof into the channel lie in contact andprevent a collapse of the channel under pr ,ssure Other means, however,may

be provided to hold the channel walls in the spaced relation necessaryfor introduction of a flashing.

From the evident that my improved flashing retainer is comparativelysimple andinexpensive in construction; provides a means permanent inVforegoing description Vit becomes character through which a metal orother character of sheet roofing may be readily introduced and securedin place without liability of its later becoming loosened and per-vmitting leakage. As to this point it is to bewnotedV thatthe width ofthe member is such as to extend into the wall in which it is supportedto sufficient distance to insure its retention and, inasmuch as themember isA laid inthe mortar, the depressions forming the inwardlyprojecting points and 7' become filled with the mortar thus insuring theretention of the retainer in place.

I claim: f 1 Y l. A flashing i'etainer consisting of a metal sheet bentupon'itself providing a narrow longitudinal channel, an edge of one sidewall being outwardly bent providing a comparatively wide threat openingto the channel, means tending to prevent the side walls from Vcollapsingunder pressure, the retainer being Aformed in strips of the desiredlength with the upper wall at one end extendingbeyond the lower wall andthe lower wall at theopposite end extending beyond the upper wall`whereby in laying the strips the projecting upper wall of one striplies over the project# ving lower wall of the other strip.

2. A hashing retainer adapted to receive the edge of aashing,;consisting ci' a sheet einen-corrosive metal bent upon itself toform a narrow longitudinal channel, 'the outer edge of the wallsdefining lthe channel being so arranged as to provide a comparativelywide throat leading to the space between the said walls, the upper andlower walls delining the channel being approximately of the same lengthandthe upper wall extending at one end to beyond the end of the lowerwall and the lower wall at the oppositeend extending beyond the end ofthe upper wall, each of said extensions having portions on the side oflthe bend extending-inwardly from the plane oit the respective wallwhereby in laying the strips the projecting end of the upper wall of onestrip lies over the projecting end otl the lower wall of the adjacentstrip with the said inwardly extending portions practically inregistration, at least one of said walls having depressions formed inits outer surface providing lugs formaintaining the walls in spacedrelation, said lugs being at aV distance vfrom the throat to permitinsertion of the -edge of a flashing.
